Abstract

This study was conducted to provide basic information for the improvement of racing performance of Jeju pony & Halla horse, using the 85,732 racing records collected from Jeju & Kwacheon racecourses from January 1, 2005 to December 31, 2009. During the last 5 years, a total of 2,892 heads of horses were racing at the Jeju racecourse and 11.7% (338 heads) of them were Jeju ponies. The average body weight of Jeju pony and Halla horse were 267 kg & 287 kg, respectively, which were 58% and 62% of that of Thoroughbred (460 kg). The repeatabilities of Jeju pony, Halla horse and Thoroughbred for finishing time were estimated in the range of 0.26-0.66 (average, 0.54), 0.34-0.68 (average, 0.56) and 0.37-0.60 (average, 0.50), respectively, and as the racing distance increased, the repeatabilities decreased. In the racing distance of 1,000 m, the differences in the finishing times between Thoroughbred & Jeju pony, Thoroughbred & Halla horse, and Jeju pony & Halla horse were 24.33 seconds, 10.81 seconds and 13.52 seconds, respectively. The racing performance of Halla horse was improved by 55.6% than that of Jeju pony at the 1,000 m race.
